Whereas source and load are mostly 50 Ω. Please keep in mind to calibrate or to measure the difference (shorted / quartz inserted).

Crystal filter - Wikipedia

A crystal filter allows some frequencies to 'bypass' through an electrical circuit while attenuating undesired frequencies. An electronic filter can use quartz crystals as resonator components of a filter circuit. Quartz crystals are piezoelectric, so their mechanical characteristics can affect electronic circuits (see mechanical filter).In particular, quartzSource apportionment of ambient fine and coarse,,May 20, 2019· A detailed description of the Quartz Filter and PUF/XAD Sample Extraction and Analysis methods can be found in Appendix B.
